Most likely:

• your kid’s prescriber is OK with 3mo fills at one time

• your prescriber may only do 1mo at a time due to their personal policy, and/or may be restricted to that by clinic policy

And:

• your husband’s schedule V is less restricted by the DEA, it can be sent to a pharmacy with refills just like a standard prescription, except limited to a total of 6 months at a time instead of 12 months for unscheduled drugs. Schedule II prescriptions cannot be sent with refills per DEA so your prescriber has to send a fresh one every time it is needed, OR can send up to 3 individual 30-day prescriptions at a time

• as far as I know pharmacies will not/cannot automatically fill your schedule II drug each month, this is likely for multiple reasons but one being that each month requires activating a fresh prescription in contrast to your husband’s, where one prescription is sent with 5 refills every 6 months that can be set to automatically fill in the system.

• you as the patient will have to contact your prescriber for new prescriptions. That’s just how it is.

• doctors do have leeway, within the laws I’ve sorta summarized above, to do what they feel is appropriate. This may be by having a personal, broad policy to only do one-month per prescription as I stated earlier; or they may decide on a case basis that an individual is too high risk to give a full 3 months at a time. The latter being because if I send in three one month prescriptions for you, then find out you’re abusing them, diverting/selling, etc. then I can contact the pharmacy and cancel the remaining ones.

In short, nothing you’ve described is anyone doing anything wrong, even though it’s a pain in your ass.
